You’re full of crap. There is no “Boogaloo movement.” It’s a media / Deep State caricature of patriot militia. The term Boogaloo was invented as a joke, gallows humor about a 2nd civil war.

IIRC, the term was also adopted in order to confound social media censorship of CWII comments. That's why there are other derivatives ("big igloo", etc.) - staying ahead of the censorship algorithm.
I agree, though, that the media has begun using it as a patriot caricature. In that sense, it's an outgrowth of the 4chan/Pepe stuff.
